Permeater PD-1C
The Permeater Gas Generator is a high-precision calibration device that uses permeation tubes and diffusion tubes to produce accurate and stable calibration gas for gas detection and monitoring systems. By maintaining a constant temperature, the system ensures a consistent release rate of both permeating and evaporating gases. With a steady flow of dilution gas such as air or nitrogen, the Permeater provides a continuous and reliable source of calibration gas, making it ideal for gas detector calibration, industrial gas analysis, and environmental monitoring applications.

Filling and setup
A diffusion tube with a fixed inner diameter is filled with a liquid substance (usually an organic solvent) using a syringe and maintained at a constant temperature.
Controlled diffusion
At the set temperature, the liquid evaporates and diffuses at a constant rate, determined by the tube’s dimensions.
Continuous gas generation
A steady flow of dilution gas (like air or nitrogen) passes through the tube, mixing with the evaporated substance to continuously generate a low, stable concentration of calibration gas.
